CHAPTER 01INTRODUCTIONIntroduction of CASTINGMetal casting is definitely one of the oldest manufacturing processes. Castings have been found dating back 6000 years. Fundamentally, casting involves filling a mold with molten material. This material, upon solidification, takes the shape of the mold. There are two basic types of metal casting processes, expendable mold and permanent mold. Castings can be made into the same shape as the final product, being the only process required. Or sometimes, casting is the first manufacturing process in the production of a multi-process manufactured part. Metal casting can be used to make parts with complicated geometry, both internal and external. With casting, intricate parts can be made in a single piece. Metal casting can produce very small parts like jewelry, or enormous parts weighing several hundred tons, like components for very large machinery. Although careful influence of casting parameters and technique can help control material properties; a general disadvantage to metal casting is that the final product tends to contain more flaws and has a lower strength and ductility compared to that of other manufacturing processes, such as metal forming.
